A Structure Analysis for Ecological Management of Moist Tropical Forests

Table 2

Stand parameters for three forest types with different logging intensities 2-Logged, 1 Logged, and Unlogged. Number of stems per hectare (), basal areas in m²/ha (), and the corresponding relative stem number () and basal area () in percentage.

Stratum	per ha	(m^2/ha)	(%)	(%)	dg (cm)	(cm)	(>60 cm dbh) per ha
2-Logged	369	29.4	26.5	30.4	31.8	84.3	29
1-Logged	530	31.9	38.0	33.1	27.7	87.4	25
Unlogged	496	35.3	35.6	36.5	30.1	87.9	24

dg: diameter of mean basal area: diameter which corresponds to the arithmetic mean of the basal area at breast height of all trees in a forest type.
: dominant diameter: arithmetic mean diameter of all trees above 60 cm dbh.
